We're currently using 15.7 SP110 on this server but I think the same thing happens on SP122 as well.
(We don't have SP132 anymore)
Indexes look like this
pk1 A, B, D, D, E, F, G clustered, unique 0 0 0 Apr 1 2015 2:54PM Local Index
ak1 C, B, A nonclustered 0 0 0 Apr 1 2015 2:54PM Local Index
ak2 B, C, A nonclustered 0 0 0 Apr 1 2015 2:54PM Local Index
Note: The table is datarow locked and have 10 partitions.
